Samsung HW-KM57C Soundbar with Wireless Subwoofer

Are the satellite speakers wireless, or just the sub-woofer?

Just the subwoofer. The satellite speakers are connected to the subwoofer.

There’s a link to the manual hiding at the top of the specs tab.

The rear speakers are connected “hard-wired” to the wireless module. The wireless module works wirelessly away the subwoofer and soundbar.

I need to ask, i have been searching reviews on the Samsung HW-KM57C now the specs provided on here say that the numbers of channels is 3.1 Ch. however i cannot find a review or a spec sheet with a spec saying the number of channels is 3.1, every spec i find says that the number of channels for this model is 5.1.

So my question is that is this model HW-KM57C a 3.1 channel or a 5.1 channel and the specs that you have posted was a typo?

EDIT*
I just spoke with Samsung and the soundbar Model HW-KM57C model does not come in a 3.1 channel with a 340 watt total power. The HW-KM57C comes with only with a 5.1 channel and a 460 watt output. The only model that comes with a 3.1 Channel and 340 watts is the Samsung HW-K550 model. sooooo are the wrong specs posted on this or the wrong model number?

The soundbar has left/center/front speakers built into the soundbar (3.1), with 2 rear satellite speakers totalling a 5.1 a setup. Plus a subwoofer. Ta-da.

Sorry for the confusion. We updated Channel and wattage info. Rest of specs looked to be correct.
